Clean WDO right?

LOL worst I have seen so far for beetles, couldn’t find a piece of wood that didn’t look like that :shock:

Looks like Anobiid.
The WDO Report is not that technical, but:

Knowing how to differentiate lyctid from anobiid damage is more than academic since anobiids have a broader range of woods that they can potentially infest. Both lyctid and anobiid ppb chew small, circular emergence holes in the surface of wood.
Holes made by lyctid beetles are about the diameter of a pinhead whereas exit holes made by anobiids are slightly larger. One way to differentiate holes of the two species is to insert a “click-type” (refillable) ball-point pen into the exit hole; only the tip of the ball will fit through a lyctid beetle emergence hole. If the hole was made by an anobiid, the tip of the pen will enter part-way up the angled face of the point.
Another way to differentiate powderpost beetles is from the consistency of the powder (frass) that sifts out of the exit holes. Lyctid frass is extremely fine and feels like talc when rubbed between the fingers. Anobiid frass is also powderlike, but feels gritty

Another method is was the frass bitter or sweet?
